The crew of a stationary spacecraft observe an asteroid whose mass is 4.00 x 1017 kg. Taking the location of the spacecraft as the origin, the asteroid is observed to be at location < 7.00 x 103, -3.00 x 103, 10.00 x 103> m at a time 18.2 s after launch time. At a time 19.2 s after launch time, the asteroid is observed to be at location < -2.10 x 103, 0.90 x 103, -5.00 x 103> m. Assuming...

Determine the angular momentum of the particle about the origin as a function of time. k kg · m2/s 6.00 і + 5.80 tj. where r ıs in meters and t is in seconds. Determine the angular momentum of the...
A spacecraft (mass of 629 kg) is 2.87 x 109 m from the center of the earth, and travelling at 3.33 x 101 (m/s) relative to the earth away from the earth. (i) What are the KE of the spacecraft relative to the earth, and the PE of the earth-spacecraft system. (ii) Has the spacecraft succesfully escaped from the gravitational pull of the earth? Hint: PE=-GMmr; G=6.67 N.m2kg2; Mass of earth M=5.97×1024kg An object undergoes SHM with period 0.9s and...
At time t1 = 16 s, a car with mass 1000 kg is located at <112, 0, 20> m and has momentum <5500, 0, −3600> kg · m/s. The car's momentum is not changing. At time t2 = 20 s, what is the position of the car?
A soccer ball of mass 0.50 kg is rolling with velocity 0, 0, 1.8 m/s, when you kick it. Your kick delivers an impulse of magnitude 1.2 N · s in the −x direction. The net force on the rolling ball, due to the air and the grass, is 0.22 N in the direction opposite to the direction of the ball's momentum. Using a time step of 0.5 s, find the position of the ball at a time 1.5 s...
1. Two asteroids collide head-on and stick together. Before the collision, asteroid A (mass 1,000 kg) moved at 100 m/s and asteroid B (mass 2,000 kg) moved at 80 m/s in the opposite direction. Use momentum conservation (make a complete Momentum chart) to find the velocity of the asteroids after the collision. 2. Two asteroids identical to those in (1) collide at right angles and stick together. "Collide at right angles" means that their initial velocities were perpendicular to each...
